It currently seems to be impossible to charge an enemy into/through a web, even if the charging character is wearing a spider cloak. Since the spider cloak makes you immune to hampering, shouldn't you be able to charge through/into webbed squares?

Charging into web with spider cloak

I noticed once the web is cast on you putting the cloak on does nothing. This basically makes this item useless. For the dungeons that have lots of web usage you do not have the cloaks and later when each of your members can have one, Resistance Cloak and blur/displacement ones are much more useful. I carried these in my inventories for a while but I figured they didn't work afterwards and sold them all.
